Driver Noise

You know that noise "doluu" that the computer makes when you plug something in and out of the USB ports (possibly other types too). Not sure how to spell that noise lol. I am hoping you know what I mean.

Well 4 days ago my computer started doing that, on and off quite often, 20 times in a minute, then nothing for maybe 10 to 20 minutes, and random times like that. I am assuming its my 360 controller, but it shows its working and all drivers are setup and everything else is good as well. It randomly started happening.
